A History of Experience,
Innovation and Reliability
As a premier industrial manufacturer, Eaton’s electrical
business is one of the world’s
leading suppliers of electrical
control products and power
distribution equipment with
yearly sales of over $2.5 billion.
Eaton’s electrical products
include a complete line of low
and medium voltage assemblies from substations,
switchgear and panelboards
to loadcenters, transformers
and safety switches. These
products are used wherever
there is a demand for electrical
power in residences, high-rise
apartment and office buildings,
commercial sites, hospitals
and factories.
Built With Experience
Powered With Innovation
Delivered With Reliability
For over a century, Eaton has
focused on providing quality
power-centric products and
services. In today’s business
environment, customers like
you are driving our transformation from a leading global
electrical components provider
into a customer-centric solutions partner who understands
your business. We do this
through in-depth collaboration
with customers and subject
matter experts studying
the issues inherent to the
electrical power distribution
and control systems.
Eaton continues to meet
changing industry needs
by providing a broad range
of automatic transfer switches.
These switches may be
grouped into a basic, enhanced
or premium set of features
that will meet your application
requirements. Eaton has
used industry-leading breakerbased designs for years and
now has a line of contactorbased designs.
Power outages due to bad
weather or utility failure have
grown increasingly costly and
more disruptive to businesses
and homeowners. A backup
power system will keep your
computers, security system,
heating or refrigeration system,
cash registers, home health
care equipment, or any system
that uses electric power,
energized and operational.
The demands for reliability have
increased. Eaton meets those
expectations by the stringent
UL姞1008 automatic transfer
switches with a world-class
product delivery system.
Eaton is one of the pioneering
electrical manufacturers
and has been focused on
providing reliable backup power
systems with transfer switch
equipment for over 75 years.
These designs can be matched
to a family of automatic transfer
switch controllers that will
meet your specific needs.
Identify your application, define
your needs, and select the
solution from Eaton.
Eaton will provide the individual
transfer switch built to exacting
standards or supply the same
transfer switch in an integrated
lineup with other Eaton gear.

The Premium Solution is
offered for those applications
requiring continuity of power
during the transfer and routine
test. This solution set offers
both contactor-based and
breaker-based designs with
drawout capability.
Basic Solution
The Basic Solution offers a
transfer switch that meets the
most basic and cost-effective
requirement needs for an automatic, manual or non-automatic
transfer switch.
This solution set allows you
to choose from either a
contactor-based or a breakerbased design and match
that power-switching device
with our basic transfer
switch controller.

Features
The automatic open transition
contactor-based transfer switch
is the most basic design that
will provide a fully functioning

An automatic open transition
transfer switch may be used for
those applications where emergency backup power is required
but a momentary loss of power
is acceptable on the retransfer
from emergency to normal.

Product Description
Features
The automatic closed transition

An automatic closed transition
transfer switch may be used
for those applications where

Product Description
Features
The automatic delayed transition contactor-based transfer
switch is used in applications
where it is advantageous to
have a time delay in the neutral
position. This adjustable delay
allows motor and transformer
loads to decay thus allowing
normal inrush currents with
the transfer.

Product Description
ATC-100 Controller
The automatic transfer switch
controller is a key component
within the automatic transfer
switch. It provides the intelligence to sense the proper
conditions to initiate a transfer
and a retransfer of the contactor.
Eaton’s Cutler-Hammer
automatic transfer switches
come with the design flexibility
of being applied with one of
three controllers. All three
controllers provide the basic
functions needed to perform
an automatic transfer.
General Description
16
The ATC-100 controller was
designed as a multi-function
microprocessor open transition
controller with simplified
customer settings. The front
panel interface displays source
availability and connection status
as well as convenient engine
start and test buttons. Controller
parameters are set via jumpers
on the printed circuit board.

Minimize initial equipment
costs, reduce installation time,
and increase system reliability.
These are goals of all involved
in placing electrical distribution
equipment in service — from
the design engineer, to the
electrical contractor, and
especially with the end user
of the equipment.
Eaton believes the transfer
switch equipment is an
integral part of the distribution
equipment. This fundamental
belief is why Eaton offers
various types of transfer
switches for the design
engineer, electrical contractor
and the user to choose from.
Eaton offers Contactor-Based,
Molded Case and Circuit
Breaker style switches.
All Eaton transfer switches
are designed to meet the
requirements set forth by UL
1008, however, all transfer
switches are not created equal.
You can be assured of safe and
reliable operation from all types
of transfer switches that
Eaton offers.
